| `[duration]` | Number of nanoseconds in the  duration     |
| `[float]`    | Value truncated at the decimal             |
| `[int]`      | Unsigned integer equivalent of the integer |
| `[string]`   | Integer equivalent of the numeric string   |

Array of values to convert. Default is the piped-forward array (`<-`).




## Examples

### Convert an array of floats to unsigned integers

```js
import "experimental/array"

arr = [-12.1, 24.2, -36.3, 48.4]

array.toInt(arr: arr)// Returns [18446744073709551604, 24, 18446744073709551580, 48]
